[XB/PS] Error Code when saving

I believe I am on an Xbox 1 or Xbox 1S and I have 368.4 MB of Sims data on my account with 174 GB free on the console. Packs I downloaded most recently (between 3-6 months ago) were the Horse Ranch pack, Enchanted by Nature/Pre-Order Content, and two kits. 

I have saves over 4 years old which I have avoided touching out of fear that this issue will delete them. This past year, I had played a little every once in a while and I only got error 34 (trying to save over an old save file and it deleted the old one) for the first time a couple weeks ago after months of not playing and I resolved the issue by creating a new save.

The game continued saving normally until today, where I have gotten error 34 consistently as well as error 21. I noticed error 34 occurs when I try to save over an old file, while error 21 occurs when I try to create a new one. My old saves are being deleted if I try to save over them and I cannot create any new files. 

I have not experienced any issues with the gallery or saving Sims to my library, but I tried the advice someone gave about deleting families/lots in my library and it did not help. Autosave is broken. 

I see that this issue goes back as far as six months, which is worrying to me as I have bought nearly every pack along with few kits. If there is no way to save the game, there is no reason to play and all these people experiencing this issue should receive refunds. 

I just got Error Code 34 as well. I couldn’t save or upload my build to my library. It allowed me to upload my Sim to the library but  it then showed it as corrupted. I’m on Xbox, all packs & kits owned and installed

I exited the game, restarted my Xbox and after loading the game back up, it asked me if I wanted to sync from Xbox storage or cloud. I chose cloud and when it loaded, my entire save file that I had been playing in had vanished.

This is the first time I have experienced this. I was playing in a new household I had downloaded from the gallery doing a fresh challenge I had set myself. I saw online that taking lots of photos can cause it and I was queuing up photos to be taken a lot during my session this evening.

I hadn’t saved for approx 4 hours when I went to go save and bug occurred.

I have tried starting a new game and loading up an old save and it appears to be working okies since restart, just missing my game file.

I had been playing in Del Sol Valley and using the cheapest camera. I had changed my lot traits and challenges frequently throughout the game session.

I'm playing on PS5, I keep getting Error code 21!

Ever since the update, every time I try to save anything from households to lots, the game freezes while saving and I have to force close it out. Once I log back in, I get an error that my save has been corrupted and it deletes every single save file I have. Even ones that I haven’t touched in over 2 years. It also deletes all of the content I have made out of my library. Content I’ve had since sims 4 first launched. I have to reload an old save from days prior. 

Every time i want to save my game I get the blue error code screen which means currently I cant play, as I have no way of saving my game! I am on ps4 as well so no mods or cc

I play on ps5 and my game is now unplayable due to every time I save my game closes and completely shuts down with an error message. I’ve spent so much money on sims and I’m devastated that this has been going on for so long with no solution 😩

Yes error code 21 and 34 it keeps popping up and it's very frustrating me and my brother have been playing the Sims4 for a very long time it won't save our files keeps disappearing so what can be done we deleted the game until it be fixed this is unfair to Xbox players 

Hi, I have been playing the Sims 4 for years on my Xbox one with no issues. I want to say with in the past couple months I have been noticing my saves diapering and/ or not saving. Just recently I have (about a month or so) been getting the error code 21 and 34 when saving, but not only that is it not saving the progress I'm working on, but it also deletes old saves. I have gone through my gallery library and delete anything I may have saved from the gallery/ I have followed so many different things to try to fix what may be happening but still nothing. At this point it I can't even play because nothing saves at all. This is my only outlet during hard times, and this week is probably the worst week 😔, I just want to play soon. Thank you for your time. 💝

Still doing the same thing this frustrating some of my family is gone and I only have one household left and it's still not letting me save my game on the Sims4 ea really needs to fix this ASAP 

Did someone figure out how to fix it
